Genes affected
NEBL (HGNC:16932): (nebulette) This gene encodes a nebulin like protein that is abundantly expressed in cardiac muscle. The encoded protein binds actin and interacts with thin filaments and Z-line associated proteins in striated muscle. This protein may be involved in cardiac myofibril assembly. A shorter isoform of this protein termed LIM nebulette is expressed in non-muscle cells and may function as a component of focal adhesion complexes. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Mar 2010]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMar 11, 2015Variant classified as Uncertain Significance - Favor Benign. The p.Gln128Leu var iant in NEBL has not been previously reported in individuals with cardiomyopathy , but has been identified in 0.2% (19/10400) of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs139809958 ). Computational prediction tools and conservation analysis do not provide stron g support for or against an impact to the protein. In summary, while the clinica l significance of the p.Gln128Leu variant is uncertain, its frequency suggests t hat it is more likely to be benign. -
not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGeneDxNov 13, 2018A variant of uncertain significance has been identified in the NEBL gene. The Q128L variant has not been published as pathogenic or been reported as benign to our knowledge. The Q128L variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Additionally, this substitution occurs at a position that is conserved across species. Furthermore, in silico analysis predicts this variant is probably damaging to the protein structure/function. A missense variant in the same residue (Q128R) has been reported in association with DCM and endocardial fibroelastosis in a newborn (Purevjav et al., 2010); however the pathogenicity of this variant has not been definitively determined. Nevertheless, this variant has been observed in approximately 0.2% of alleles from individual of African ancestry in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server; Exome Aggregation Consortium). -
